VALVE.

SPECIFICATION forming part of Letters Patent No. 745,099, dated November24, 1903.

Application filed May 12, 1903. Serial No. 156,797. (No model.)

To all whom it may concern.-

Be it known that 1, ANDREW CLARENCE FAMBROUGH, a citizen of the UnitedStates, and a resident of Sonora in the county of Sutton and State ofTexas, have made certain new and useful Improvements in Valves, of whichthe following is a specification.

My invention is an improvement in valves, and especially in valvesdesigned for use in tanks; and the invention consists in certain novelconstructions and combinations of parts, as will be hereinafterdescribed and claimed.

In the drawings, Figure 1 is a sectional elevation of my improveddevices as in use. Fig. 2 is a detail. section on about line 2 2 of Fig.1, parts being broken away; and Fig. 3 is a detail perspective view ofparts of the device.

The tank A may be of ordinary construction and has the outlet-pipe Bextended slightly within the tank and threaded to receive thevalve-guide O, which also furnishes at O the seat for the valve D. Tothis end the valveguide O is providedlin its under side with the socketat O to receive the threaded end of the pipe B and has the reducedopening forming the valve-seat O, as will be understood from Figs. 1 and3 of the drawings. The valve-guide O is in the form of a flattened oroval ring, providing the base-bar C having the Socket 0 and the seat 0,and the top bar O having an opening in line with the opening O toreceive the bushing E, which is provided at its lower end with a headand is inserted from the under side through the opening in the top bar Cand is threaded to receive the nut F, which secures the yoke G in placeon the projecting upper end of the bushing E, as shown in Fig. 1. Thevalve D has its stem D extending up through the bushing and above thesame and has swiveled on its upper end the coupling H, provided with thelugs H, to which are pivoted the inner ends of the lever-arms I, saidlevers being pivoted between their ends on the upwardly-projecting armsG of the yoke Gr and being connected at their outer ends with the floatJ by the wires or rods K, as will be understood from Figs. 1 and 2.

By the described construction it will be noticed the yoke II isswiveled, so it can freely turn upon theupper side of the valve-guide,and the coupling H is swiveled on the valvestem and concentrically withthe pivot of the yoke, so the valve will not be displaced" or affectedby any turning or swinging of the levers Elaterally within the tank. Itwill also be noticed that if the tank be full, as shown in Fig. 1, thevalve will be closed by the action of the float through the connectingmeans described. It will also be noticed that when the float lowers tothe desired extent the valve will be opened.

The construction is simple, easily applied to a tank, and theconstruction and arrangement of valves are such as will work in shallowwater and permit a much greater flow,

because the valve can be adjusted to a wideopen position.

While it is preferred to employ the two opposite lever-arms I, as shownin the drawings, it will be understood that one of said arms may beomitted and the device operated by a single lever-arm when so desired.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The improvement of valves herein de scribed comprising thevalve-guide in the form of a flat ring having the lower bar pro videdwith the valve-seat communicating with the discharge, and the upper barprovided in line with said seat with an opening for the bushing, thebushing fitting in said opening and extended above the valve-guide, theyoke swiveled on the upwardly-projecting portion of the bushing andprovided at its ends with the upwardly-projecting arms, theretaining-nut on. the bushing above the yoke, the valve having its stemextending through the bushing and above the same, the coupling swiveledon the upper end of the valve-stem, the levers connected at their innerends with the coupling and pivoted between their ends to theupwardlyprojecting arms of the yoke, the float and connections betweenthe float and the outer ends of the arms substantially as set forth.

2. The herein-described improvement in valves consisting of the fiatring having upper and lower bars, the lower bar being provided with avalve-seat and the upper bar in ICO line with said seat With an openingfor the bushing, the bushing fitting in said opening in the upper barand projecting above said bar, the yoke swiveled on theupwardly-projecting portion of the bushing and havingupwardly-projecting arms at its opposite ends, retaining means on thebushing above the yoke, the levers pivoted between their ends to thearms of the yoke, the valve, connections between said valve and theinner ends of the levers, and the float connected with the outer ends ofthe levers substantially as and for the purpose set forth.

3. The combination substantially as herein described of the fiat ringhaving upper and lower bars and having its lower bar provided With avalve-seat and its upper bar With an opening for the bushing, saidopening being in alinelnent with the valve-seat, the bushing fitting insaid opening in the upper bar and threaded to receive the yoke retainingnut and having a central opening for the valve-stem, the yoke resting onthe upper bar of the ring and swiveled on the bushing and provided atits ends with upwardly-projecting arms, the nut on the bushing above theyoke, thevalve having its stein projecting upwardly through and abovethe bushing and the levers pivoted on the upwardly-projecting arms ofthe yoke and connected at their in ner ends with the valve-stem and thefloat substantially as and for the purposes set forth.

ANDREW CLARENCE FAMBROUGH.
